I modified the XMBean persitence example to add support fpr remote access via JNDI by adding the folowing to META-INF/jboss-service.xml

<!-- Proxy factory for MyService that will call invoke(Invocation mi) on the target service -->
<mbean code="org.jboss.invocation.jrmp.server.JRMPProxyFactory"
name="jboss.jmx:type=adaptor,name=MyService,protocol=jrmp,service=proxyFactory">
<!-- Use the standard JRMPInvoker from conf/jboss-service.xxml -->
<depends optional-attribute-name="InvokerName">jboss:service=invoker,type=jrmp</depends>
<!-- The target MBean -->
<depends optional-attribute-name="TargetName">jboss.jmx:service=PersistentServiceExample</depends>
<!-- Where to bind the proxy factory -->
<attribute name="JndiName">PersistentServiceExample</attribute>
<!-- Invoke invoke(Invocation mi) operation instead of the target method -->
<attribute name="InvokeTargetMethod">true</attribute>
<!-- MyService interface -->
<attribute name="ExportedInterfaces">org.jboss.jmx.examples.persistence.PersistentServiceExampleMBean</attribute>
<attribute name="ClientInterceptors">
<interceptors>
<interceptor>org.jboss.proxy.ClientMethodInterceptor</interceptor>
<interceptor>org.jboss.proxy.SecurityInterceptor</interceptor>
<interceptor>org.jboss.jmx.connector.invoker.client.InvokerAdaptorClientInterceptor</interceptor>
<interceptor>org.jboss.invocation.InvokerInterceptor</interceptor>
</interceptors>
</attribute>
</mbean>

If i try to access methods on the proxy object from within a web application I get the followin exception:
